During startup, my camera indicates the gimbal motor is overloaded, but there are no obstructions. After trying to go through the startup process about five times, the camera is working. During flight, the camera will shake violently in all directions and to the limits of travel. This will occur for several seconds then stop. The camera then begins to tilt the image slowly for about a second, then begins to shake violently again. This repeats over and over. Do I have to send this in or is there a fix I can do myself?
